Fastboot and adb are similar but distinct from each other. You should use "fastboot flash recovery <nameoftwrpfile>.img" but I would recommend reading/practicing up on fastboot, abd, and that command. Also, before dottat corrects me, use of htc_fastboot is recommended although not required for all fastboot functions.
